I have lost my seed phrase before but later I found it. I lost it because I was alone in the house and family was on vacation for the last Christmas Holiday and since I was alone I drop the seed phrase paper under the parlour center table. And I forgot to remove it so when the children came they saw it there and use it the book to write their nursery rhymes and misplaced the book as we. So for the time when I wanted to use the seed to login to another device I could not find it again and I look for this paper for three months and finally I saw it under the bed. And the advice I will give here is that even though you are alone in the house always keep your seed phrase in save place and secret place because you don't know when a visitor will come to the house and picked the seed phrase from your house. Always be security conscious.
